Honeywell L7000: Finding the MAC & CRC

Our informative video shows you how to find the MAC and CRC numbers, which you’ll need to connect your home alarm system to the monitoring company.

The connection between your home security system and the monitoring provider is your lifeline to assistance. If an alarm is activated, the company will be able to take appropriate action. This might be a confirmation call to your house or an instant request for help from local emergency officials.

You want a secure connection which is reliable and difficult to tamper with. Our video guide shows you how to connect your system to the alarm company, which means identifying the unit’s MAC and CRC numbers.

Identifying these addresses is one of the first actions you’ll take when setting up your L7000. The security company uses this info to reach your device.

As the video details, you can use a wireless, cellular or wired connection. The Honeywell L7000 is compatible with the L5100 Wi-Fi Communicator, the GSMVLP-5G Cellular Communicator, the 3GL Cellular Communicator and the ILP5 Hardwired Communicator.

With the hard-wired communicator, you’ll run a physical Ethernet cable from your security panel back to your router. Logistically, this can be difficult, depending on where your router is located relative to the main control panel.

The Honeywell L7000 allows for two different Communicators, but only in certain combinations. Wi-Fi and Cellular are allowed as are Wi-Fi and Wired. Cellular and wired will not work together.

Many people prefer using Wi-Fi and Cellular. You can avoid the hassle of running an Ethernet cord through your house. But you can still have the peace of mind found with two separate Communicators. If your internet connection goes out, a cellular connection lets the unit still provide information to the alarm company.

Regardless of what you choose, each device will have both a MAC and a CRC. You can find them in two ways: physically and through the control panel.

Each device will have both the CRC and MAC on a sticker. The info will also be on the box. But if your device is already installed, or you’ve discarded the boxes, you can also easily pull the info from the control panel.

The video explains how to do so. Using your Installation Code, you’ll enter the Programming Page. The video then shows you how to navigate the Programming area to find the Communication ID Numbers.

You’ll see the numbers for each Communicator. The video goes into great detail about what the numbers mean. Each setup is different so you’ll want to consult the video for specifics.

Basically, the type of device will be labeled in parenthesis as Wi-Fi, GSM and so on. The type of device is listed in columns while the rows show MAC, CRC and Wi-Fi. Don’t worry if that layout description sounds a bit confusing. Seeing a real display in the video is easier to understand.

This information is vital to establishing the monitoring portion of your home security system. Fortunately, pulling the info from your home device is pretty simple with our video tutorial.
